Title: Observing method for metal lographic/structure
Inventor: MINEMI MASAHIKO
IPC: G01N23/225
Filed: 1993-12-06
Abstract: PURPOSE:To definitely discriminate base phase from the secondary phase by forming a carbon-containing film on the surface of metal lographic/structure, so that transmission of the secondary electron generated on the surface is prevented, for later observation. CONSTITUTION:With an Al phase 1 as the base phase, an Si phase 2 which is the second phase is allowed to present itself as a non-conformity phase. When the surface is irradiated with electron beam 3 for an extended period, a carbon-containing film 5 originating from organic substance in the atmosphere is generated. The secondary electron 4 of short flying range generated at the Al and Si layers near the surface is impossible to be observed as is shielded with the containment film 5. Meanwhile, reflection electron 6 caused by the electron beam 3, as opposed to the secondary electron 4, is generated more at the Si phase 2 than the AL phase 1. The reflection electron 6 releases the secondary electron 4 from the surface layer, and relating to the image through a scan-type electron microscope, the part of Si phase 2 becomes, opposed to normal case, brighter than that of Al phase 1, with definite discrimination possible between them. This is accurately converted into numerical values with a picture analyzing device.

The rotating force of the motor 1 is also transmitted to a bell hitting cam 31 through a gear train 32. When the time is set in this way, a driven piece 25 in the switch 22 is brought up to the high stage part of a first track 15 in a cam 9, so that the cams 8, 9 are axially moved by the energizing force of a spring 13. Namely, the driven piece 25 is laid in the state bestriding over both the first track 15 and second track 16 in the cam 9. When the set time passes in this state, and the main shaft 2 is returned to the cut position, in each mechanism, the switch 18 is opened to cut the current to the load 48.
